5. In a machine of the character set forth, the combinationwith aspindle andv a deof-the-way position.

'6. In a machine of the character set forth, the combination with aspindle and adetachable bearing therefor, of a carrier for supportingthe bearing on the machine frame while out of operative relation to thespindle comprising an upright bracket, a

relatively short arm pivoted on said bracket so as to turn on a verticalaxis, and a relatively long arm pivoted at one end to the free end ofthe short arm and pivotall secured at its .other end to the upper sioe01' the bearing.

7. In a moulder or the like, the combination of a detachable spindlebearing, ways on which said bearing is normally supported, a carrier forsupporting the bearing on the machine frame for movement into and out ofoperative relation to the spindle, and means for adjusting the bearingin a vertical direction relative to said ways.

8. A moulder or the like having a main frame, a spindle having bearingson the frame one of which is. detachable from the spindle, a slideway onthe frame adapted to guide said detachable bearing for movement axiallyof the spindle, and means swingable on the frame for supporting saiddetachable bearing when disengaged from for movement into a position. aone side the spindle.

9. A machine of the character described having, in combination, a baseframe, bearings thereoma spindle rotatably mounted in said bearings andcarrying a cutting tool which is removable endwise off the spindle, oneof said bearings being slidably mounted on said base and removable fromthe spindle by movement in a direction axially off one end of saidspindle, means for guiding said removable bearing out of and intosupporting relation to said spindle, and a carrier therefor, of acarrier for said spindle .to permit thebearing-to move first in astraight line axially off-the spindle and then to swing laterally to apositionat one side of the spindle whereby to permit removal andreplacement of the cutting tool on said spindle.

10. A machine of the character described I having, in combination, abase frame, a spindle, bearings for said spindle mounted on portions ofsaid base frame which directly underlie said spindle, one of saidbearings being removable from the spindle by movementin a directionaxially oif one end of said spindle, and a carrier for said removablebearing movably mounted on said base and permanently connected to saidbearing, said carrier acting to support said bearing for movement fromoperative to inoperative position and vice versa, and the carrierembodying a pivotal joint which permits the bearing to be swung to saidinoperative position at one side of the spindle after the bearing hasbeen withdrawn in an axial direction from the spindle.

11. A machine of the character described having, in combination, a baseframe, bearings thereon, a spindle rotatably mounted in said bearings,one of said bearings being removable from the spindle by movement in adirection axially off one end of said spindle, guideways on said basefor guiding said removable bearing out of and into supporting relationto said spindle, a carrier pin on which said removable bearing isivotally and permanently supported, and means mounted on the base forsupporting said. carrier pin for movement in a direction to permit thebearing to pass axially onto and off the spindle.

12. A machine of the character described having, in combination, a baseframe, a pair of bearings thereon, a spindlev rotatably mounted in saidbearings and carrying a cutting tool which is removable endwise ofi' thespindle, one of said bearings being mov able relative to the base andthe other hearing by movement in a direction axially of said spindle,guideways on said base for guidingsaid movable bearing axially of saidspindle, and a carrier for said movable hearing permanently attached tosaid bearing and movably mounted on said base, and operating in themovement of said bearing to permit first the movement of the bearingaxially of the spindle and then a pivotal movement of the bearing to aposition whereby to permit withdrawal and replacement of said cuttingtool.

13. A machine of the character described V having in.combination, a baseframe, a pair of bearings thereon, a. spindle irotetably in saidbearings and carrying a cutting tool which is removable endwise ofi thespindle, one of said bearings being slidably mounted on'said base andremovable from the spindlein a direction axially ofi one end ofsaidspindle, guideways on said base for guiding said removable bearingqxially of bearing comprising a pair of said spindle, and a carrier forsaid movable ivotally con nected links, one of said li s being pivotallyattached to said bearing and the other of said links being pivotallysupported on said base frame In testimony whereof I have hereuntoaflixed my signature.
